In the Linux kernel, the following vulnerability has been resolved: dev/parport: fix the array out-of-bounds risk Fixed array out-of-bounds issues caused by sprintf by replacing it with snprintf for safer data copying, ensuring the destination buffer is not overflowed. Below is the stack trace I encountered during the actual issue: [ 66.575408s] [pid:5118,cpu4,QThread,4]Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: do_hardware_base_addr+0xcc/0xd0 [parport] [ 66.575408s] [pid:5118,cpu4,QThread,5]CPU: 4 PID: 5118 Comm: QThread Tainted: G S W O 5.10.97-arm64-desktop #7100.57021.2 [ 66.575439s] [pid:5118,cpu4,QThread,6]TGID: 5087 Comm: EFileApp [ 66.575439s] [pid:5118,cpu4,QThread,7]Hardware name: HUAWEI HUAWEI QingYun PGUX-W515x-B081/SP1PANGUXM, BIOS 1.00.07 04/29/2024 [ 66.575439s] [pid:5118,cpu4,QThread,8]Call trace: [ 66.575469s] [pid:5118,cpu4,QThread,9] dump_backtrace+0x0/0x1c0 [ 66.575469s] [pid:5118,cpu4,QThread,0] show_stack+0x14/0x20 [ 66.575469s] [pid:5118,cpu4,QThread,1] dump_stack+0xd4/0x10c [ 66.575500s] [pid:5118,cpu4,QThread,2] panic+0x1d8/0x3bc [ 66.575500s] [pid:5118,cpu4,QThread,3] __stack_chk_fail+0x2c/0x38 [ 66.575500s] [pid:5118,cpu4,QThread,4] do_hardware_base_addr+0xcc/0xd0 [parport]
